- Method Detail
  - interpolate
```
MultivariateFunction interpolate(double[][] xval,
                                 double[] yval)
                          throws MathIllegalArgumentException,
                                 DimensionMismatchException,
                                 NoDataException,
                                 NullArgumentException
```
    Computes an interpolating function for the data set.
    
    Parameters:
    
    xval - the arguments for the interpolation points. xval[i][0] is the first component of interpolation point i, xval[i][1] is the second component, and so on until xval[i][d-1], the last component of that interpolation point (where d is thus the dimension of the space).
    
    yval - the values for the interpolation points
    
    Returns:
    
    a function which interpolates the data set
    
    Throws:
    
    MathIllegalArgumentException - if the arguments violate assumptions made by the interpolation algorithm.
    
    DimensionMismatchException - when the array dimensions are not consistent.
    
    NoDataException - if an array has zero-length.
    
    NullArgumentException - if the arguments are null.
